Hi Everyone

I installed my Gigabyte B450 Aorus M motherboard yesterday and wanted to do some mild overclocking on my Ryzen 5 2600. When I go into the bios of this motherboard and can't seem to change any of the CPU settings, they are locked on Auto and the base clock speed of the 2600. I can change any other settings fine, just not one's specific to the CPU clock speed and frequency.

I could be missing something very simple here, if so I'd be grateful if any of you kind people can explain what's happening and how to rectify it.

Many thanks in advance.

What BIOS version are you working with on the motherboard at the time of writing? On another note, what cooler are you working with to cool the processor? You're going to dump heat into your chassis so you'd need to make sure the processor is cooled, while the airflow should also be optimal to aid in cooling the VRM as well as extract the heat from the case.

Show some BIOS screenshots (upload to imgur.com and post link).
You're probably on BIOS easy mode. Switch to advanced mode first.
How do I switch to advanced mode, I can't seem to find an option anywhere.

Current bios version is F50, and I'm using a Noctua NH-U12S CPU cooler. I have 2 x 120mm intake fans and 3 120mm exhaust fans running in my PC.

My problem isn't cooling as far as I'm aware, the current issue is not being able to change any of the CPU clock, frequency and voltage settings.
 
Well you should be able to Overclock the Ryzen 5 2600 there is no reason the MB Bios should prevent that either.
You may not have as many Bios options as with higher end Boards but a moderate Overclock is achievable.

Your Bios has Advanced Frequency Settings in the M.I.T SECTION and if selected provides for CPU core ratio and other advanced frequency settings. Core voltage under Advanced voltage settings.

Ensure your Bios and chipset are up to date. You should achieve around 4GHz with good case ventilation and a decent CPU cooler. Around 4.2 using water cooler.

I cannot do anything to change CPU clock, frequency and voltage. Just been in the bios again and I have easy mode and classic mode, cannot see anything related to an advanced mode. Just wondering if downgrading the bios may be an option to unlock CPU setting adjustments. I'm totally at a loss, unless there is something really plain and simple I am missing. I'm not a novice when it comes to overclocking a system, I have done it a number of times before, but something is stopping me from being able to make adjustments to the CPU parameters, and I have no idea what. Would a CMOS reset be a possible solution?
 
I've consulted your MB manual and page 23 shows menu structure listing advanced features.
Although I don't advocate Ryzen Master others have Overclocked using this app.
Maybe you do have to revert back to another Bios?
Clearing CMOS would just bring Bios back to default.

Thanks for your advice.

I am familiar with Ryzen Master, I actually find it quite a good utility, I was just hoping to change settings in bios so as to have the OC in place permanently, and to not have another background process running when using my PC.

As far as rolling back the bios goes, any ideas on how far back I should go?
 
I would try them all if Overclocking is important to you. You should not have to do this and I would contact Gigabyte and find out why.
The problem with using a third party app such as Ryzen Master is that you should not also interact with Bios as you can corrupt Bios.

CPU Clock Ratio setting (shown in 2 of screenshots) - change from Auto to manual and input desired value.
CPU frequency is calculated from CPU Clock ratio and can not be changed directly.

CPU Clock Control - leave on Auto.
I am aware of what I need to do, the problem is that I can't physically change these values from Auto to Manual. I double click the mouse on them, or highlight the value that I want to change and press enter on the keyboard and absolutely nothing happens, it's like these settings are locked.

iv got the same problem i can only see easy mode an classic how do i get to advanced mode is the a keyboard shortcut button in uefi or boot up i should press

plus iv got the ARCTIC Liquid Freezer II 120 with a noctua 120mm 3000rpm fan an the aio pluged in to the cpu fan header but no read in uefi bios is it even being powered id like to run the pump at 50% an have a temp curve set to ramp when needed there only to sys fan headers on the mobo an ther pluged into a SilverStone Technology Silverstone 8-Port PWM Fan Hub/Splitter each is running a set of my noctua fans should i plug the aio power into one oh them would the system then read an control it right now the system in bios only show two rpm values one for each sys fan header , if i used a fan connector splitter between the silverstone pwm control cable an the aio's an connected that to one of the sys fan headers would that then the pump an both sets of fans



















aftermarket heatsink inplace of original the riitop houses a 2nd 500gb nvme drive (any thoghts on wheither i should run in raid mode for them)




im going to use a brush to paint the spots i missed with spray cans a touch up the fan frames an ram heatsinks later

I have the ARCTIC Liquid Freezer II 120 connected on my aorus b450 m there's no pump header so I have it plugged into the cpu fan Header but in the bios it reads 0 rpm under the
smart q fan control,id like to know two things 1 can I safely assume that the pump is powered.

even though thers no rpm read , and if I set the cpu fan at 50% in the fan graph from 20c to 35c an then up to 60% from 35c an up to ramp when needed can I safely assume that the pump is doing that
or I'm I wrong with both assumptions , an if so should I plug the aio pump into the sys fan header instead to get desired results.

I'm not using the stock aio fan I'm using a noctua 120mm industrial 3000rmp model for a pull config an I have it plugged into a Silverstone fan splitter/hub not though the aio's fan passthough connector as to aio's pump rpm is stated as a max of 1800rpm vs the fans 3000rpm.

is ther a external pump controller that I can use for the aio that will give rpm control and status
